AIEngineeringTool guide: sequential sheet-metal flat pattern
Original guidance on flange/bend data, bend allowance, developed length and production validation.

Original guidance on flange/bend data, bend allowance, developed length and production validation.
Source: Original AIEngineeringTool educational content; production bend-test data remains controlling.
Workflow
- Create N bend records and N+1 connected flange records.
- Use each bend's approved K-factor, radius and angle to calculate allowance and deduction.
- Use the same result object for the folded SVG, flat pattern, bend lines and developed length.
Engineering review boundary
Use controlled material data, actual load conditions and the applicable design code. This guide supports preliminary calculation understanding; it does not certify a design.
